SEC Filings

On
December 10, 2015, BioTime entered into a lease for 30,795 square feet of office and laboratory space in two buildings located
in an office park in Alameda, California (the “Alameda Lease”). The term of the Alameda Lease is seven years and BioTime
has an option to renew the term for an additional five years. BioTime moved into the facility and the term of the Alameda Lease
commenced effective February 1, 2016.

Base
rent under the Alameda Lease on February 1, 2018 was $68,673 per month, and will increase by approximately 3% annually on every
February 1 thereafter during the lease term. The lease payments allocated to the lease liability for leasehold improvements reimbursed
by the landlord are amortized as debt service on that liability over the lease term.

In
addition to base rent, BioTime will pay a pro rata portion of increases in certain expenses, including real property taxes, utilities
(to the extent not separately metered to the leased space) and the landlord’s operating expenses, over the amounts of those
expenses incurred by the landlord. As security for the performance of its obligations under the Alameda Lease, BioTime provided
the landlord with an initial security deposit of approximately $847,000, which was reduced by $423,000 on February 1, 2018 pursuant
to the lease agreement, and will be further reduced by an additional $346,000 after the first thirty-six months of the lease term,
by applying those amounts to future rent payment obligations under the lease, if BioTime is not in default under the Lease. The
security deposit amount under the Alameda Lease is considered restricted cash (see Note 2).

New
York Leased Office Space

BioTime
currently pays $5,050 per month for the use of approximately 900 square feet of office space in New York City, which is made available
to BioTime for use in conducting meetings and other business affairs, on a month-by-month basis, by one of its directors at an
amount that approximates his cost.

Cell
Cure Lease

Cell
Cure has leased 1,128 square meters (approximately 12,142 square feet) of office and laboratory space in Jerusalem, Israel under
a lease that expires between May 30, 2019 and December 31, 2020, with two additional options to extend the lease for 5 years each.
Base monthly rent is NIS 63,402 (approximately U.S. $18,247 per month). In addition to base rent, Cell Cure pays a pro rata share
of real property taxes and certain costs related to the operation and maintenance of the building in which the leased premises
are located.

On
January 28, 2018, Cell Cure entered into another lease agreement with its current landlord for an additional 934 square meters
(approximately 10,054 square feet) of office space in the same facility in Jerusalem, Israel under a lease that expires on December
31, 2025, with two additional options to extend the lease for 5 years each (the “January 2018 Lease”). The January
2018 Lease commenced on April 1, 2018, and includes a leasehold improvement construction allowance of up to NIS 4,000,000 (approximately
up to $1.2 million) from the landlord. The leasehold improvements are expected to be completed by September 30, 2018. Combined
base rent and construction allowance payments, assuming the full allowance is utilized, for the January 2018 Lease will be NIS
93,470 per month (approximately $27,000 per month) beginning on October 1, 2018.
